We had no school on monday, On tuesday we watched the Presidential inaugeration. On wednesday, we had a test. That narrows it down to thursday and friday. On thursday, we went over the lab. This was the onion root lab. We saw the different phases of the cell replication. This is important because it shows how we make more cells. The cells double their chromosomes and make another cell. On Friday, we learned that the correct term for this was called mitosis. Then we did a cell simulation of the different phases of mitosis on the computer. I learned that spindle fibers pull apart the chromosomes and make new cells with just the right amount of chromosomes in each cell.
